This week has been destroyed by workshops and my last death throes with a paper I am submitting on my research in New Zealand. And to think, I thought it might settle down a little after the students left. To news! Ash fall on a taxi cab near Guatemala’s Pacaya. Pacaya in Guatemala erupted yesterday…

For all of you going into withdrawal now that Eyjafjallajökull seems to have quieted down, there are two eruptions of note that aren’t in the North Atlantic: Undated image of the Barujari cone at Mt. Rinjani in Indonesia. Arenal in Costa Rica – which is almost always sputtering away – had a more significant explosive…

The small steam plume from Eyjafjallajökull on May 23, 2010, where explosive eruptive activity has ceased for now. The big news over the weekend, at least volcanically, was that Eyjafjallajökull seems to have entered a period of relative quiet. The eruption has died down dramatically, with the last ash explosion occurring two days ago. Since…

News, news, news! Ash from Eyjafjallajökull piling up on a roof at Seljavellir. Image courtesy of the IMO, by Ari Tryggvason. The latest from Eyjafjallajökull has the volcano continuing to puff away – producing intermittent airspace closures over Europe. The Icelandic Met Office reports a ~7 km (21,000 foot) ash plume, but they note that…

Part 2 of your recollections of the May 18, 1980 eruption of Mount St. Helens. You can read Part 1 here. You can also check out an amazing set of satellite images spanning 1979-2010 at the NASA Earth Observatory. Great stuff! ————————————————————————————————- Eruption plume from Mount St. Helens on May 18, 1980. Image courtesy of…

Some news for a sleepy Monday: Mt. Hood in Oregon. The ash from Eyjafjallajökull is, once again, causing significant airspace closure over northern Europe – close of 1,000 flights today. However, much of the closures are fairly short-lived, but that isn’t keeping people happy. The eruption hasn’t actually changed much, just that the winds are…

May 18, 2010 marks the 30th anniversary of the dramatic eruption of Mount St. Helens in Washington state. Now, rather than recount the event when the USGS and the Cascade Volcano Observatory have done such an excellent job, I turn it over to all the Eruptions readers and their memories of the eruption. Now, as…

An aerial view of Eyjafjallajökull erupting on May 11, 2010, with the extent of the black ash from the eruption on Gígjökull clearly evident, along with the cracks in the glacier near the lava flow. Photo from the Icelandic Met Office, by Sigurlaug Hjaltadóttir. Since this past weekend’s disruptions due to Eyjafjallajökull, the air over…

I an in the home stretch for grading exams, so just a quick update for today: The evidence of floods from the Eyjafjallajökull eruption, taken on May 1, 2010 by Dr. Joe Licciardi. Airports now as far south as Spain, Morocco and the Canary Islands are facing closures due to the Eyjafjallajökull ash. The latest…

A shot of the summit area of Eyjafjallajökull, showing the twin steam-and-ash plumes from the lava flow and active vent. Picture taken by Dr. Joseph Licciardi (UNH). Over the weekend, the newly reinvigorated ash eruptions from Eyjafjallajökull combined with favorable winds meant that ash from the eruption closed airspace over swaths of Europe, including Ireland,…
